Abstract

In a method of selecting one station from a set of stations dialoging with a main station, the main station consults groups of stations one at a time, sending a consultation message to each group consulted. Within each group, stations having information to transmit request reservation of a multiplex link time slot connecting the group to the main station. Each station having information to transmit makes this request after a time delay which depends on the address of the station within the group has elapsed since reception of a synchronization signal. When the main station consults a group, only the station which has reserved this multiplex link can send over the link. In a system implementing this method, each group of stations comprises a self-assigned bus and a synchronization signal link. Each station comprises an assignment system connected to the self-assignment bus and to a microproccessor in the station.
